Procedure

To a solution of tert-butyl 4-(4-fluorobenzyl)-4-hydroxypiperidine-1-carboxylate (2.0 g) in ethanol (10 mL) was added 2.0 M HCl/ethanol solution (20 mL), and the mixture was stirred at room temperature for 3 hr. The solvent was evaporated under reduced pressure, and the obtained solid was recrystallized from ethanol/hexane to give the title compound (1.4 g).
